SHUTTLE-OPERATING MECHANISM FOR LOOMS.

SPECIFICATION forming part of Letters Patent No. 438,996, dated October21, 1890.

Application filed April 10, 1890. Serial No. 347,371. (No model.)

To aZl whom it may concern.-

Be it known that I, FINIS E. FISHER, a citizen of the United States,residing at WVaco, in the county of McLennan and State of Texas, haveinvented new and useful Improvements in Shuttle-Operating Mechanism forLooms, of which the following is a specification.

This invention relates to looms, and has for its objects to providenovel, simple, and efficient mechanism for actuating the pickingstickswhich effect the flight of the shuttles; to avoid the use of theordinary lower pickershaft; to avoid lateral-angles in thepickinglevers, which actuate the picking-sticks to throw the shuttles,and to otherwise improve the picking motion of looms for obtainingsimplicity, strength, durability, power, and efficiency.

To accomplish all these objects, my invention involves the features ofconstruction, the combination or arrangement of devices, and theprinciples of operation hereinafter specifically described, and recitedin the claims, reference being made to the accompanying drawings, inwhich- Figure 1 is a top plan view showing sufficient of a loom toexhibit my invention. Fig. 2 is an elevation of the same partiallybroken away at one side to show a picking-lever and a picking-cam actingthereupon.

In order to enable those skilled in the art to make and use myinvention, I will now describe the same in detail, referring to thedrawings, wherein Thenumerall indicatesa portion of aloomframe, 2 theshuttle-boxes, 3 the lay, and 4 the lay rock-shaft, all of which partsmay be of any known construction, and therefore require no furtherexplanation.

A horizontal duplex crank-shaft 5 is journaled in boxes 6 on the sidesof the loomframe, and is provided near each end with a miter-gear 7,between which gears the cranks 8 of the shaft are located. The shaft atone end is provided with a fast or driving pulley 9 and a loose or idlerpulley 10, and the mitergears respectively mesh with similar mitergears12, attached to picking or counter shafts 13, arranged at right anglesto the axis of rotation of the crank-shaft and respectively placed nearthe sides of the,loom-frame. The

counter-shafts are journaled upon supporting brackets or hangers 14, andeach is provided with a picking-cam composed, as here shown, of a disk15, attached to the shaft and provided with an eccentric roller-stud 16to act upon the upper end of a picking-lever 17, which is supportedintermediate its extremities by a rock-shaft or other pivotal support18, carried by a bracket 19 on the side of the loom-frame. Thepicking-levers, one at each side, can oscillate, and they connect bylugging-sticks 20 with the picking-sticks 21, which are pivoted at theirlower ends to bearings 22, carried by the lay rook-shaft. A spring 23,of any suitable type, is connected with each picking-stick to restorethe same to its normal position after having been actuated by thepicking cam and lever to throw the shuttle. The cranks 8 of the shaft 5are connected by pitman 24 with the lay 3, and thus the shaft serves toimpart the required swing ing motion to the lay, in addition torevolving the picking or counter shafts.

In the drawings the parts are in the position occupied when onepicking-stick is restored to its normal position and the other is at thelimit of its stroke which throws the shuttle.

By the combination or arrangement described the two independent pickingor counter shafts are arranged at right angles to the axis of the duplexcrank-shaft, and the latter not only swings the lay, but operatesthrough the miter or bevel gears to continuously revolve the picking orcounter shafts, thereby causing the picking-cams on the latter toactuate the picking-levers for positively imparting the shuttle-throwingstrokes to the picking-sticks.

By my invention I avoid the use of the usual lower picking-shaft anddispense with lateral bends in the picking-levers.

Having thus described my invention, what I claim is- 1. The combinationof aloom-frame having brackets or hangers, a horizontal revolving mainshaft, a pair of revolving picking or counter shafts geared to the mainshaft, journaled in the brackets or hangers on the loomframe at rightangles to the main shaft, and each carrying a picking-cam, thepicking-levers pivoted intermediate their ends to the loom-frame andacted on at their upper end portions by the picking-cams, thepickingsticks, the lugging-sticks connecting thelower ends of thepicking-levers with the picking, sticks, and the springs connected tothe picking-sticks, substantially as described.

2. The combination of the lay, the crankshaft connected with the lay andhaving a pair of miter-gears, the picking-shafts arranged at rightangles to the axis of the crankshaft, respectively geared to themiter-gears thereon, and each having a picking-cam composed of a diskand an eccentric roller-stud, the pivotedpicking-levers, thelugging-sticks; I 5 the picking-sticks, and the springs, substantiallyas described.

In testimony whereof I have affixed m y signature in presence of twoWitnesses.

FINIS E. FISHER.
